Solution Overview

Problem

Golfers face the inconvenience of carrying a separate golf ball marker while wearing a watch, such as a smartwatch, during their game, which disrupts their play.

Innovation Solution

A buckle clasp for a watch bracelet integrates a removable golf ball marker housed in a compartment with magnetic and/or mechanical clamping means, allowing easy access and secure retention within the clasp.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a separate golf ball marker is carried during play, then the golf ball can be marked, but it disrupts the player's game and causes inconvenience

Engineering Contradiction:
Improveconvenience of carrying golf ball markerVSAvoidnumber of accessories to carry
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the golf ball marker function with the watch bracelet clasp by integrating a housing into the clasp structure that can accommodate a golf ball marker. This merging eliminates the need to carry a separate marker while maintaining the clasp's primary function, directly resolving the contradiction between convenience and accessory complexity

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If the golf ball marker is securely retained in the clasp, then it remains in place during play, but it must still be easily removable for marking golf balls

Engineering Contradiction:
Improvesecure retention of golf ball markerVSAvoidease of removing golf ball marker
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces traditional mechanical retention systems with magnetic retention, where a magnet in the housing holds the golf ball marker securely during play, yet allows easy removal when needed. This magnetic system resolves the contradiction by providing both secure retention and ease of operation through non-contact holding forces

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables golfers to conveniently carry and use a golf ball marker without additional accessories, ensuring it remains securely in place during play and is easily removable for marking golf balls.

Implementation Method 1

clamping means, the clamping means providing magnetic and/or mechanical clamping, configured to retain the removable golf ball marker in the housing

Methodology Applied
